VistaDB 5






ExtendedType Property
Flag to represent that this column is an extended data type (it is stored separately from the rowdata of non-ExtendedType columns).
Syntax
'Declaration
 
ReadOnly Property ExtendedType As System.Boolean
'Usage
 
Dim instance As IVistaDBColumnAttributes
Dim value As System.Boolean
 
value = instance.ExtendedType
System.bool ExtendedType {get;}
read-only property ExtendedType: System.Boolean; 
function get ExtendedType : System.boolean
__property System.bool get_ExtendedType();
property System.bool ExtendedType {
   System.bool get();
}
Remarks
Image, Text, and NText (also known as VarBinary(MAX), VarChar(MAX), and NVarChar(MAX)) are all normally stored as extended row data because they cannot necessarily fit within the row data space (smaller values might be stored with other row data when they do fit). Extended columns can be slower to search, sort etc as extra disk seeks and row loads are required to operate against these columns.
Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
